Legal claims defining the scope of protection, as filed with the USPTO.
1. A temporary payment instrument, the temporary payment instrument comprising: a target material; and a one-dimensional barcode printed on the target material, wherein the barcode is less than three inches wide, and a 16-character payment card account number and an eight-character expiration date associated with a payment card are encrypted into the bar code by compressing each character of the account number and the expiration date from a respective eight-bit binary sequence into a respective four-bit binary sequence such that the account number and expiration date are recoverable from the bar code.
2. The temporary payment instrument of claim 1 , wherein each of the characters is a space, a forward slash, or one of the digits 0-9.
3. A temporary payment instrument, the temporary payment instrument comprising: a target material; and a one-dimensional barcode printed on the target material, wherein the barcode is less than three inches wide and a string of at least 24 characters is encrypted into the bar code such that the string of characters is recoverable from the bar code, and the string of characters includes a payment card account number and an expiration date associated with a payment card, wherein the string of characters is encrypted into the bar code by compressing each character in the string from a respective eight-bit binary sequence into a respective four-bit binary sequence.
4. The temporary payment instrument of claim 3 , wherein the string of characters includes a 16-digit payment card account number and an 8-digit expiration date associated with the payment card.
5. The temporary payment instrument of claim 3 , wherein each of the characters is represented by a four-bit binary sequence.
6. The temporary payment instrument of claim 3 , wherein each of the characters is a space, a forward slash, or one of the digits 0-9.
7. The temporary payment instrument of claim 3 , wherein the target material is a paper.
8. The temporary payment instrument of claim 3 , wherein the string of characters is encrypted into the bar code using a symmetric encryption algorithm.
9. The temporary payment instrument of claim 3 , wherein the string of characters is encrypted into the bar code using an asymmetric encryption algorithm.
10. The temporary payment instrument of claim 3 , wherein the string of characters is encrypted into the bar code using elliptical curve encryption.
11. A method for generating a barcode for a temporary payment instrument, the method comprising: converting a string of at least 24 characters into a payload by compressing each character of the string from a respective eight-bit binary sequence into a respective four-bit binary sequence; encrypting the payload; generating a one-dimensional barcode representing the encrypted payload, wherein the barcode is less than three inches wide and the string of characters is encrypted into the bar code such that the string of characters is recoverable from the bar code; and printing the barcode on a target material.
12. The method of claim 11 , wherein the payload is encrypted using a symmetric encryption algorithm.
13. The method of claim 11 , wherein the payload is encrypted using an asymmetric encryption algorithm.
14. The method of claim 11 , wherein the payload is encrypted using elliptical curve encryption.
15. The method of claim 11 , wherein the string of characters includes a payment card account number and an expiration date associated with a payment card.
16. The method of claim 11 , wherein the string of characters includes a 16-digit payment card account number and an 8-digit expiration date associated with a payment card.
17. The method of claim 11 , wherein each of the characters is a space, a forward slash, or one of the digits 0-9.
18. The method of claim 11 , wherein the target material comprises a paper.
19. A temporary payment instrument, the temporary payment instrument comprising: a target material; and a one-dimensional barcode printed on the target material, wherein the barcode is less than three inches wide and a string of at least 24 characters is encrypted into the bar code such that the string of characters is recoverable from the bar code, and the string of characters includes a payment card account number and an expiration date associated with a payment card, wherein the string of characters includes a 16-digit payment card account number and an 8-digit expiration date associated with the payment card.
20. The temporary payment instrument of claim 19 , wherein each of the characters is represented by a four-bit binary sequence.
21. The temporary payment instrument of claim 19 , wherein each of the characters is a space, a forward slash, or one of the digits 0-9.
22. The temporary payment instrument of claim 19 , wherein the target material is a paper.
23. The temporary payment instrument of claim 19 , wherein the string of characters is encrypted into the bar code using a symmetric encryption algorithm.
24. The temporary payment instrument of claim 19 , wherein the string of characters is encrypted into the bar code using an asymmetric encryption algorithm.
25. The temporary payment instrument of claim 19 , wherein the string of characters is encrypted into the bar code using elliptical curve encryption.
